[plt-scheme] Drscheme boost programs performance

Nice to hear this. For a moment this thread worried me, for I always run 
from DrScheme (usually debugging switched off and modules first compiled 
with managed-compile-zo and debugging switched off) I hate typing shell 
commands and I love the simple way PLT Scheme can be downloaded/installed 
and the way DrScheme can be used without having to worry about shell 
scripts/commands (untill a decade ago I was an expert in producing reliable 
scripts, though)

>From time to time, I experience severe slow downs too, but they can always 
be tracked down to Fsecure and HP-digital-monitor (under Windows XP that is) 
Even in a completely clean system, without any application running, they 
sometimes consume 25% of CPU time. When I really want all of my CPU, I first 
restart my system without connection to any network and without printer, 
virus protection and firewall.
Thanks, Jos
